INDIANA INSULATOR.

SPECIFICATION- forming part of Letters Patent No. 660,140, dated October 23, 1900. Application Sled April 9, 1900. Serial 110.12.083. (No model.)

To u/ u-mm it may (foncez-1L.-

lle it known that I, CASSIUS ALLEY, of Pendleton, county of Madison, and State of Indiana, have invented a eert-ain newand useful Insulator; and l do hereby declare that the following is a full, clear, and exact description thereof, refe-rence being had to the accompanying drawings, in which like ligures refer to like parts. I

This linvention relates to insulators for mountingr electrical wires for telegraph, telophone, or other use.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims.

In tlie drawings, Figure 1 is a perspective of one-half of said insulator. Fig. 3 is a longitudinal central section of tho insulatorcomplete. Fig. 3 is a section on the line A A of Fig. 2. Fig. t isa plan of one-half of the insulator with the wire mounted thereon. Fig. 5 lis a central cross-section ot" the insulator Fig. 6 is an end view of the insulator' mounted in place and held by a nail. Fig. 7 shows the insulator suspended byn wire. Fig. S shows the m'aiu wire mounted on the insulator bya loop-wire instead of. extending centrally through it. Fig. J shows the manner ol' applying onedialf of the insu-lator to the corner of a building or block about which the main wire extends. Fig. l() shows the manner ofstrin; ,'iin`r a fencewirc. Fig. l1 shows the maunerof sti-inging a wire directly to the top of a pole.

Referring now to the details of form and construction of said insulator and to tite mean.`l and lnannerof mounting the same and applying it to .tet-ual usc, 1 represents one of the halves of said insulator, which madeI of glass, porcelain, or other insulating material. It consists of a corrugated outer sur` face having the recesses 2 for the purpose of obtaininggreaterinsulation. llxtcndingcentrallyand longitudinally through the inner flat facoof said hall'oi the insulator there is a semi-elliptical groove 3, flaring scmieireular at its ends.. Across said llat surface at the end there are recesses l and near the opposite end lugs 5 of such dimensions as to lit snugly in recesses of the same size as said recesses 4.` Around thehalf of the insulator a groove ,ing grooves t on the other half.

and cent-rally through the insulator.

G is placed about centrally between the two ends.

The half described in the above paragraph constitutes the article of manufacture and sale embodied in this invention. In use generally two of such parts or halves are placed with their iiat. faces together andwith the lugs 5 on each lhalf iitting in the correspond- This holds them from independent longitudinal movement., as appears in Fig-. When the two vhalves are thus placed together, the longitudinal grooves 3i register with each other and form an elliptical passage way centrally through the insulator as a whole, as seen in Figs. 2, il, and

In the most common method of using such insulator the two halves thereof are placed about. the main wire 7, as seen i'n Fig. i, and a. small tie-wire t; inserted through the hole 3 an .l coiled at each cnd about the main wire to-provide stops to limit the longitudinal movementof the wire Z through the insulator. The ends of the tie-wire are turned down to prevent the water running along the main wire through the insulator. The insulator is secured to the cross-arm t) by providing said cross-arm with an opening 1l through it. large enough to insert tite insulator and then insertinga nail l2 in tfhe hole 1S in the cross-arm, so that it will rest in l-ho groove U ou the side of the insulator, as appears in Fig. (i. As there shown, an insnlating-washcr 13 is provided for the head of the nail. The corrugations on the insulatorpt-rtnit their heilig easily driven in ifthey 'vary somewhat in dimension, as the wood will yield for the ribs'of the insulattn'. This means `or method of mounting the insulator is very rapid and cheap. No trouble is required in placing thcinsulator, as both 'naires are alike and can be instantly pnt. in piace about the wire. l`u'rther:nore, the insulator furnishes a strong andeasy support for the wire, as the latter extends longitudinaliy \\'hen the insulator is mounted, as shown in Fig. t3, it is protected from destruction. Also the water will drop off the wire when arranged as shown in Figs. -l and 7 without going in or entering the insulator, Then in the po- 1 sition shown in Fig, 6,

. arm smooth fdr standing rounds the insulator,

n econo or sitting positions of linemen. There are other advantages, which, however, it is needlessV here to suggest to those skilled in the art of Stringing telephone and telegraph wires.

In Fig. 7 a means for suspending the insua tree or otherobject is shown. It consists merely of a wire 14, coiled once about the insulator, tit-ting in the groove and attached at the other end to the means of support, whatever that may be. -This illustrates a great advantage of the insulat-orherein shown.

In Figs. 5 and 10 a Vmeansnnd method is shown for Stringing fence-wires for telephone use, as is quite common now. The insulator is held to the post 9 by a staple 10, that eurandthe barbed fencewire 7 extends through the insulator.A By making the insulator ot two parts it is possible thus to string a barbed wire.

1 Figs. 83nd 11 show a means and method of mounting a wire directly toa pole. There the insulator is secured to the pole 15 or other support by'a screw centrally through it, and the telephone-wire 7 is held horizontally in the groove G at one sido against the insulator by a loop-Wire 16, that iiisabont the insulator in the groove 6.

In Fig. 9 there is shown a means and method ofsupportin'ga telephone-wire from the rightangled corner of a buildingY or block; where the wire turns the. corner. It is useful also forstringingtheinterior-.ofbuildings. There only one-half the insulator is used. The groove 3 tits on the corner of the block 17, and the wire extends on the outside ofthe insulator, tting in the'groove G.

It is obvious, therefore, from the description given of the torm and uses of said in- Sulator that it is'an important advance -in the art because of its cheapncss, simplicity, ease of manipulation, and extensive adaptability lo the various needs of persons Stringing electric jwires. It effects quite a saving in tie- )vires By making the passage-way 3 through the insulator elliptical in cross-section about xnidway between the ends of the passage-way Lne tie-Wire cannot revolve around the main .Wire whilethe tie-wireis being coiled or at any other time. Withthis arrangement the tiew're will remain always in the position in it leaves the cross-l A ing the ends of the which it left, ann lne ends of the tie-Wire are turned down to prevent Water entering the insulator. The elliptical forni ofthe passage-way through the insulator will 'retain the tie-wire in such position. Also by makpassage-way 3 daring and preferably round :ne .insulator can be held in the hole ll in the cross-arm without the use of the nail lz? or other moans. This is because any pull. onthe wire through thcinsalator will canse the halves of the insulator to spread somewhat and bind it all the tighter in the cross-arm. This spread is causedV by the coil ofthe tic-wire being drawn into the flaring end of the passage-'way and tending to push the halves of the insulator apart, and it is preferable to so place the insulator in the cross-arm or other wooden support that the spread of the insulator would be in line with the grain of lhc wood, so as to prevent splitting the wood in which the insulator is mounted, as appears in Fig. (i.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. An insulator provided with a passageway throughit,a conductor extending t h rough said passage-tray anda tic-wire extending through said passage-way with its ends coiled about the conductor near the ends of the insulator.

2. An insulator provided with a passageway through it that is elliptical in cross-scci tion, a conductor extending through the passage-way with its ends coiled aha-ni the conductor near the ends of the insulator whereby the tie-wire cannot revolve around the conductor.

' 3. An insulator provided with a passageway through it that is elliptical in cross-section in its middle portion with its ends flaring, a conductor extending through the pas sage-way, and a tie-wire extending through said passage-way with its ends coiled about the conductor near the ends of the insulator and turned at their extremities.

In witness whereof l have hereunto affixed my signature in the presence of the witnesses herein named.
